Test principle and measuring method of friction coefficient of drilling fluid lubrication tester

Abstract This paper introduces the test principle of the friction coefficient, and then introduces its measurement method, which provides a theoretical basis for the overall design of the tester. We propose the following scheme: design a set of DC pulse width modulation (PWM) servo control system wi...
